Villarrica may refer to:
Villarrica (/ˌviːəˈriːkə/ VEE-ə-REE-kə) (Spanish: Volcán Villarrica, Mapudungun: Ruka Pillañ) is one of Chile's most active volcanoes, rising above the lake and town of the same name, 750 km (470 mi) south of Santiago. It is also known as Rucapillán, a Mapuche word meaning "Pillan's house". It is the westernmost of three large stratovolcanoes that trend perpendicular to the Andean chain along the Gastre Fault. Villarrica, along with Quetrupillán and the Chilean portion of Lanín, are protected within Villarrica National Park. Guided ascents are popular during summer months.
Villarrica, with its lava of basaltic-andesitic composition, is one of a small number worldwide known to have an active (but in this case intermittent) lava lake within its crater. The volcano usually generates strombolian eruptions with ejection of incandescent pyroclasts and lava flows. Rainfall plus melted snow and glacier ice can cause massive lahars (mud and debris flows), such as during the eruptions of 1964 and 1971.
Villarrica is a town and municipality in the Tolima Department of Colombia. The population of the municipality was 5,903 as of the 1993 census. Most workers work in agriculture or cattle ranching. The altitude is 863 meters above sea level.
The Villarrica region was inhabited in pre-Columbian times by the Cuindes and Cundayes. Villarrica was hidden behind the Andes mountain range and a thick forest, and the indigenous population was to a great extent undisturbed until 1920, when Don Francisco Pineda López founded an estate called Villarica. The municipality is named after this estate.
